LMPROVEMBH'I IN PARA-TUB F03 RED'D'CHIG- FIBROUS, TO A swoon.

The, Schedule referred to in those Letters Patent and making port of the ammo.

T 0 all whom-it may concern Be it known that I, Lonnnzo Dunn, of Fort Edward, in the county of Washington and State of New York, have-invented a new and improved Machine for Assisting in Reducing Fibrous Material to a Textile Stock; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying draw ing making a part of this specification, in which-- Figure I is a plan .view, and

Figure 2 is a side elevation.

This invention has for its object the disintegration of the fibers of Esparto grass, straw, orother fibrous material, to a condition in which it is ready to undergo a further disintegrating process by a chemical solu tion in a'hoiler, which process is fully described in another application made by"m e for a patent, and which produces a textile stock which may be spun, woven, or felted, or reduced to a pulp "for the manufacture of paper and for other purposes.

The invention consists in a mill for crushing and brooming, and thus disintegrating the fibrous mate rial alter the same has had one or more sonkings-in tepid water, for the purpose of dissolving the waxy, glutinous substance surrounding the fiber and removing therefrom a portion of its color, the construction andoperation of the said mill being hereinafter fully explained.

The invention also consists in a process of soaking the fibronsmaterial lntepid water whilepass'ingthrough the machine.

In the drawing- A is'the cast-iron fi'Itl'Il8-\\0l'k of the machine. B is a cylinder, mountedtransversely of the frame- 7 work A, and having circular flanges b b at its ends.

0 is a second cylinder, mounted transversely of the frame-work A, above and to the rightof the cylinder B,

i between the flanges b of the same, and nearly in. contaot with it.

D is a. third cylinder, mounted, in relation to the cylinder B, in all respects similarly as the cylinder 0 is mounted, except that the cylinder I) is to the 1c of the cylinder 13.

Spur-gears in 0d, fixed on the projecting ends of the shafts of 'the cylinders B O D, outside the framework A, transmit the motion of the cylinderllt to the cylinders G D- The cylinder B receives mot-ion troni a crank, e.

E is an inclined apron, placed crosswise of the.

frame-work, the said aprou having side flanges f j, which make of it a guide-way for .the soaked fibers,

that conduct the same directly against the periphery of the roll B, just below the passage, between it and the upper roll D.

The diameter of the rolls B and D are about the .While passing between these two cylinders the fibrous material is pressed flat, nnd a portion of its waxy, glutinous element, and of its color, removed by such pressure. The material thereupon emerges il.lt 0 the chamber between tho-three cylinders B O D, which space is kept filled with fresh tepid water by any suitable apparatus. The material, therefore, receives another soaking while passing this chamber, but is squeezed Hat and nearly dry again while running between the cylinders B and G.

The cylinder 0 is of greater diameter than the roll 13, and therefore moves faster at its surface, and, by

such faster movement, it stretches, thus partially disintegrating the fibers as they pass between it and the cylinder B. I

F i's-a vertical block, placed crosswise of the framework A, at the opposite side of the roll B from the apron E, and beneath the cylinder C.

The block F bears at the upper and inner corner a scraper, h, which scrapes and keeps clean the surface of the cylinder B.

'At the upper and. outer corner of the block' E are knives, fixed lengthwise of the same.

i is a shaft, mounted parallel to the series of rollers and. the block F, and bearing, fixed lengthwise of its surface, a series of blooming-knives, i, which approach, in their rotation, very near the bed-knife, on the block F.

The nbrons material, while on its way to the brooming-knives, receives a second soaking in 'tepi water, similar to the first.

While passing between the bed and incomingknives the fibers are still further disintegrated, which completes the operation of this machine.

Having thus described my invention,

What I claim, and desire to secuie by Letters Patcut, isv v,

1. The combination of the cylinders B O D, framework A, apron E, block F, provided with the scraper and bed-knife, and shaft 1, provided with thebroomlug-knives i, all substantially. as and for the purpose described.

2. The combinatiop of the rolls "(3 and B, when the former is of greater diameter than-tho latter, in order that the fiber may be partiallydisintegrated while passing between the two rolls, substantially as described.

3..The process, herein described, ot soaking the fibrous materiahin' tepid water while passing through the machine.
